Definitions
- the invention relates to an identity card, in which symbols such as alphanumeric characters, patterns, images or the like, are designed in relief, and a method for producing a badge with a relief structure.
- ID cards are used in many areas. For example, they are used as credit cards, bank cards, bank cards and the like in cashless payment. Provided with appropriate identification features, they can also be used as identification cards for their owner. On the one hand, because of their widespread use, they are typical mass-produced articles, that is, their manufacture must be simple and inexpensive, but on the other hand they must be designed to be as much protected against counterfeiting and falsification as possible. In addition, the data stored on them should be easy and secure for both machines and people.
- ID cards are known in which information in the form of relief-like characters are imprinted on the card.
- the relief-like signs can be felt by humans, on the other hand they can also serve as a printing block to transfer the information from the card to paper.
- EP 308 904 it is known to provide a card, which can be made of PVC, among other things, by surface treatment with different features by differently guided laser processing. described In particular, the application of foamed embossing marks in surface plateaus, the application of flat characters on a card surface by discoloration and the application of visually verifiable authenticity features on a card surface.
- a two-layered card surface material whose cover layer is transparent, it is also possible to cause foaming and discoloration at the same time.
- the production of such two-layered card surfaces increases the overall card manufacturing effort.
- An ID card consists of a plastic material or is provided with a surface layer of a plastic material which is mixed with chemical or physical blowing agents. By a laser beam, the plastic layer is heated locally and foamed. The locally foamed areas form a relief structure on the card surface.
- EP 1 113 131 A2 it is known to produce tactile characters by embossing and then to blacken the raised embossments with a laser.
- the blackening can be exactly on the surveys, so that a positive writing arises, or be made in between, so that a negative writing arises. Due to the blackness, the relief-like embossed tactile signs are also visually perceptible.
- the object of the present invention is therefore to propose an identification card with a relief structure made of foamed plastic and a method for its manufacture, in which the relief structure is visually easily recognizable.
- An identity card according to the invention has a card surface with a relief structure made of foamed plastic.
- the relief structure can represent tactile symbols in the form of alphanumeric characters, patterns, images or other graphic structures.
- the identification card can consist overall of a plastic which can be foamed locally by supplying energy, for example by irradiation with a laser beam.
- the foamable plastic may, for example, be mixed with chemical or physical blowing agents. Suitable plastics are listed for example in DE-OS 24 50 948, DE-AS 26 50216, DE-AS 2921 011 and DE-OS 3213 315.
- the ID card can also have only one card surface a layer of foamable plastic, over the entire surface or only locally.
- the identity card according to the invention is characterized in that the relief structure forming the symbols is bounded by a contour of discolored plastic.
- an area of discolored plastic is located adjacent to the relief structure in a non-foamed, flat area of the card surface.
- dicoloration or “discolored plastic” is understood here to mean that the card surface is specifically discolored, in particular darkened, by suitable treatment, for example by irradiation with a laser, in comparison to surrounding, untreated areas of the card surface.
- the "discolored” areas may be black or they may merely have a different color or gray shade than the untreated areas.
- the contour of discolored plastic can be directly adjacent to the relief structure. Alternatively, between the relief structure and the contour made of discolored plastic there may be a narrow area of undyed, unaufschuftäumtem plastic.
- the relief structure of foamed plastic does not need to be discolored on its own, but only in an unfoamed area of the card surface is a contour of discolored plastic provided, the problem of discoloring foamed plastic may have to be avoided.
- the contour of discolored plastic, the relief structure which in turn is preferably not discolored, optically well visible.
- an identification card is provided in which a relief structure is tactile as well as visually easy to perceive.
- the relief structure needs to be partially bounded by the contour of discolored plastic. It is sufficient for an improved visual recognition already that each relief structure area is bordered only on one side of the discolored contour. This results in an optical impression of a shadow in oblique lighting.
- the contour completely surrounds the relief structure. That is, each self-contained relief texture area, such as each letter or number, is completely enclosed by the contour. In this way, a very good visual perception is ensured from different viewing angles.
- the contour has a uniform width.
- a contour can be formed from a line surrounding the relief structure with a uniform width of a few hundred micrometers. Due to the uniform width of the contour results in a uniform, well-perceived and pleasant for the viewer appearance of the contour.
- the card surface may be made of a single plastic material which may be in a foamed state as well as a discolored state. Which of these states the plastic material takes depends on the processing of the plastic material, as described below. As a plastic material are inexpensive and easy to process materials such as PVC or polyester, ABS or mixtures thereof into consideration. In addition, however, relatively expensive materials such as polycarbonate or mixtures of expensive and inexpensive materials, such as polycarbonate with PET / PETG, can be used.
- the inventive method for producing a badge card assumes that the badge has a plastic material which can be foamed on the one hand by introducing energy, i. increases its volume, and on the other hand, if the energy is supplied in a different way, can change its color, for example, by setting a blackening of the plastic material.
- the method according to the invention is particularly suitable for producing the identity card according to the invention and realizing its optional features described above.
- the method according to the invention comprises two steps: on the surface of the identification card, a foamed relief structure is formed by introducing energy in a first energy supply mode in foaming regions in a first manner; discolored contours are created around the foaming regions by introducing energy in a second energy delivery mode in a second manner.
- the energy is preferably supplied by irradiation with a laser beam.
- the laser emitting laser may be suitably operated in various ways and with different power settings to enable different energy delivery modes.
- the laser can work in particular (quasi) continuously (cw operation) or clocked.
- the respective energy supplied by the laser can also be influenced by adjusting the power of the laser beam, the wavelength and frequency of the laser light, the residence time of the laser beam on a surface area of the card to be treated and / or the focusing of the laser beam.
- the steps of creating the frothed relief structure and creating the discolored contours may be performed in any order. For example, first the relief structure can be foamed and subsequently the discolored contours can be created around the relief structure. Alternatively, the discolored contours can first be generated and then the relief structure can be foamed in the areas bordered by the contours. Preferably, during the production of the discolored contours, the regions to be foamed or the already foamed relief structure are not irradiated with the laser beam.
- the contours can be formed as continuous, uniformly wide contour lines around the foaming areas around. By avoiding that the laser beam also irradiates the foaming areas to produce the discolored contours, it is possible to prevent the discolored contours at their transition to the foaming areas from having an irregular, frayed boundary which disturbs the visual appearance of the contours.
- Such a frayed boundary may result in an alternative embodiment of the method according to the invention, in which a laser beam is guided both over the foaming areas and over adjoining areas to be discolored in order to produce the discolored contours.
- the laser beam can have a width which is greater than the width of the foaming areas, so that the laser beam projects beyond the foaming areas and discolored contours can be generated on both sides of the foaming areas.
- the discolored contours extend directly to the foamed relief structure. Since these can not be discolored or a previously existing discoloration 'at least partially disappears when the plastic material foams up, the discolored contours have a boundary which corresponds to the inverse boundary of the relief structure. Experience has shown that the latter is irregular or frayed due to the foam structure.
- the laser for generating the foamed relief structure is vectorially controlled and the laser radiation is applied quasi-continuously. brought.
- the laser energy is expediently applied in a screened manner in a pointwise manner by operating the laser in a pulsed mode.
- a suitable web guide of the laser can be provided as part of the vectorial control.
- the laser can follow the lines of a grid, in the course of which the laser beam is guided several times over the crossing points of the grid.
- both the foamed relief structure as well as the discolored contour can be applied by a controlled grid operation, in which case the laser parameters are switched between the two processing steps.
- the two processing steps of producing the discolored contour and the production of the foamed relief structure can advantageously be carried out on a single processing station, wherein the laser can be guided twice over the card in correspondingly different settings.
- a great advantage of this embodiment is that the complicated positioning of the card must be made only once.
- the process according to the invention can be carried out on inexpensive, easily processed plastic material, such as, for example, PVC or polyester, in particular in the form of PET or PETG.
- plastic material such as, for example, PVC or polyester, in particular in the form of PET or PETG.
- the person skilled in the art knows how the energy must be introduced into the plastic material, for example, how the laser has to be matched in terms of its power, its wavelength and / or its operating mode to the plastic material used, in one case to foam the plastic material lead and in the other case lead to a discoloration of the plastic material.
- FIG. 1 shows an identification card designed according to the invention
- Figure 2 is a schematic sectional view of a contoured relief structure
- FIGS. 3a, b show a comparison of a conventional relief structure with a relief structure formed according to the invention
- FIG. 4 schematically shows a basic principle of the method according to the invention, in which a foamed relief area is surrounded by a discolored contour area;
- FIG. 5 schematically shows an alternative basic principle of the method according to the invention, in which a larger area of contour area is superimposed overlapping a smaller relief area;
- FIG. 6 schematically shows a basic principle of a further embodiment of the method according to the invention.
- FIG. 1 shows an identity card 1 with a relief structure 3 contoured according to the invention and further inscriptions 5 and illustrations 7.
- the ID card 1 has at least one plastic card surface on which one or more tactile symbols are formed. Symbols are understood to mean alphanumeric characters as well as graphic shapes and patterns in general. The tactility of the symbols becomes achieved by forming a relief structure. The symbols are divided into a central area and a border area. In the central area, the relief structure is formed. It consists of foamed plastic and has the inherent color of the plastic or at most has a slight discoloration compared to the intrinsic color. The edge region is flat to the map surface and compared to the intrinsic color of the plastic clearly discolored, so that the relief structure is contoured.
- FIG. 2 shows a sectioned relief structure 3 in section.
- foamed relief structure 8 which forms the central area of a symbol
- discolored areas which lie in the edge region of the symbol and form a contour 9 around the foamed relief structure 8.
- the laser is guided along a first path which traces the central regions of the symbols.
- the laser is guided along a second path, which is derived from the first.
- the order of production of foamed relief structure 8 and contour 9 is freely selectable .
- the illustrated relief structure 3 was generated experimentally with a brand FOBA DP20GS laser, on the one hand, on a card 1 made of PETG, the laser being operated with a diode current of 28A and a frequency of 55 kHz.
- the laser was moved at a web speed of 7000 mm / s along the lines of a grid formed by three lines intersecting at 45 ° and 90 °, respectively; the line spacing was 0.07mm.
- a dot density of 465 dpi was set.
- the relief structure 3 was produced on an identification card 1 with a PVC core on which a cover layer made of a mixture of PET and PC was applied.
- foamed relief structure 8 and discolored contour 9 were both generated in gerereus operation.
- the laser was operated with a diode current of 26A and a frequency of 55 kHz.
- a dot density of 500 dpi was used, and to create the discolored contour 9 a dot density of 465 dpi was set.
- An enlargement of the contoured relief structure 3 is shown in FIG. 3b.
- the contoured relief structure 3 according to the invention is visibly easier to see visually.
- the path control of a laser which can be used to produce the discolored contours 9 presents a particular challenge in the production method according to the invention.
- the path traveled to produce the foamed relief structure 8 can not simply be repeated.
- four exemplary solutions are proposed:
- a sample card with a foamed relief structure 8 is produced and then measured geometrically. From the measured values, path control data for the contour 9 are generated. The method gives very good results, but is expensive.
- Path control data for generating the contour 9 are computationally generated from the path control data for generating the relief structure 8, for example by adding an amount taking into account the width of the foamed relief structure 8 to the existing control data.
- the Method requires in order to provide optically good results, very complex algorithms and therefore is preferably suitable when only one consisting of a few simple symbols contoured relief structure 3 is to be formed.
- FIG. 4 shows a region 11 to be foamed, within which a laser beam is traversed following a path.
- the properties of the laser beam are chosen so that energy is supplied to a card surface material such that it forms a foamed relief structure.
- control data for generating a contour line 13 are calculated.
- the laser is then adjusted in its properties so that it introduces energy into the card surface material such that it turns black.
- the laser beam is directed along the calculated contour lines. The result is a black-framed relief structure 15.
- the card surface is made of a plastic which can not be discolored once it has been foamed by laser action
- the width of a discoloring laser beam is made wider than the width of a laser beam used to form the foamed relief structure.
- the web used to produce the foamed relief structure 8 can be easily traced.
- the edge regions of the symbols projecting beyond the foamed relief structure 8 are then discolored in a contour-like manner, so that the contour 9 is formed, while the foamed relief structure 8 itself can not be inked or at most slightly colored.
- FIG. 5 shows an example of a superposition of a relief structure 21 with a larger-area contouring structure 23. Both structures are in one One-line character set executed. This results in the outline-shaped relief sign 25th
- the web used for the production of the foamed relief structure 8 is repeated several times, the web being displaced by a certain amount at each repetition to the original web used for the production of the foamed relief structure 8.
- the offset is preferably in the symbols associated main directions, typically in + x, -x, + y, -y direction.
- Figure 6 shows an example in which a wider, "richer” character 33 is generated from a first pattern 31 by displacing the pattern as used to create the relief structure 31.
- This fatter character 33 is used to generate trajectory data used by the laser during the blackening and superimposed on the foamed relief structure 8. This results in a black outlined relief sign 35.
- a suitable definition of the offset such as omitting a main direction, a similar shadow effect can be achieved, as shown in Fig. 3b is shown.
- a foamed relief structure 8 and in a further step, a surrounding, discolored contour 9 is generated, which allows Solution according to the invention a number of other modifications.
- other plastic materials into consideration which can be foamed and discolored.
- the specified processing parameters can be varied in order, for example, to have higher foamed relief structures 8 or to achieve a greater processing speed.
- the parameters also depend on the laser actually used and the purpose of the contoured relief structure 3.
- the solution according to the invention is not limited to identity cards, but is equally suitable for plastic cards with a different function and with arbitrary formats for telephone cards, entrance tickets or gift cards.
